On the find my friends app why is the orange circle sometimes bigger than other times
Why is the orange circle around a person in find my friends app sometimes larger than others? It seems like my daughter in New York always has a larger circle and is harder to pinpoint where she is. Is that due to the dense population there or lots of building interference? Or could be due to her phone battery being weak or a weak signal?
